Day after day we are discovering new things and both debunking old theories and proving new theories. One of the latest? There is a vast Ocean hidden deep down inside the earth – maybe over 400 MILES deep inside Mother Earth!
A battered diamond that survived a trip from “hell” confirms a long-held theory: Earth’s mantle holds an ocean’s worth of water. “It’s actually the confirmation that there is a very, very large amount of water that’s trapped in a really distinct layer in the deep Earth,” said Graham Pearson, lead study author and a geochemist at the University of Alberta in Canada. The findings were published today (March 12) in the journal Nature.
The worthless-looking diamond encloses a tiny piece of an olivine mineral called ringwoodite, and it’s the first time the mineral has been found on Earth’s surface in anything other than meteorites or laboratories. Ringwoodite only forms under extreme pressure, such as the crushing load about 320 miles (515 kilometers) deep in the mantle.
